C++ 窗体透明度设置

透明度的设置实在pFunc里面的那个200的值 它的取值范围是0～255 0表示全透明的
255表示不透明
SetWindowLong(m_hWnd,GWL_EXSTYLE,GetWindowLong(m_hWnd,GWL_EXSTYLE)^0x80000);

HINSTANCE hInst = LoadLibrary("User32.DLL");

if (hInst != NULL)

{

typedef BOOL (WINAPI *MYFUNC)(HWND, COLORREF, BYTE, DWORD);

MYFUNC pFunc = (MYFUNC)GetProcAddress(hInst, "SetLayeredWindowAttributes");

if (pFunc != NULL)

{

pFunc(m_hWnd, 0, 200, 2);

}

FreeLibrary(hInst);

hInst = NULL;

}
